COMPOSITE IMAGE SIGNAL CIRCUIT
COMPOSITE IMAGE SIGNAL CIRCUIT
DescriptionINFOID:0000000003765934
AV control unit that inputs the camera image signal and AUX image signal transmits the composite image sig-
nal to the display unit.
Diagnosis ProcedureINFOID:0000000003765935
1.CHECK CONTINUITY COMPOSITE IMAGE SIGNAL CIRCUIT (AV CONTROL UNIT TO DISPLAY UNIT)
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector and display unit connector.
3. Check continuity between AV control unit harness connector and display unit harness connector.
4. Check continuity between AV control unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK COMPOSITE IMAGE SIGNAL (AV CONTROL UNIT TO DISPLAY UNIT)
1. Connect AV control unit connector and display unit connector.
2. Turn ignition switch ON.
3. Check signal between AV control unit harness connector using an oscilloscope.
Is inspection result normal?
YES >> Replace display unit.
NO >> Replace AV control unit.
